  • MarcOnt Initiative Tools for collaborative ontology development Maciej Dąbrowski , Sebastian Ryszard Kruk Digital Enterprise Research Institute National University of Ireland, Galway maciej . dabrowski @deri.org
  • Outline
    • Motivation
    • Ontologies in the world of digital libraries
    • MarcOnt Tools
    • MarcOnt Portal
    • Future work
  • Motivation
    • World of Digital Libraries
    • Identified Problems:
    • Interoperability
    • Format translation
    • Multiple data formats in DL:
    • How to support them?
    • How to translate between them?
    • Who should create mappings?
  • Real-life problems – user’s expectations
    • Searching:
    • Effective and Accurate
    • We want correct and fast answers!!
    • Intuitive and Simple
    • Asking questions should be easy.
    • Meaning
    • Jaguar – a car or an animal?
    • Reasoning
    • Give me articles written by students of X in Galway?
    • Identified problems:
    • Intuitive interface for asking complex querries
  • Real-life problems - summary
    • Digital Libraries should provide:
    • Interoperability
    • Support for many formats
    • Complex search features
    • Intuitive interfaces

  • MarcOnt Initiative
    • Motivation:
    • Build a bibliographic ontology for
    • the Jerome Digital Library
    • MarcOnt Initiative goals:
    • Deliver a set of tools for
    • collaborative ontology
    • development
    • Collaboration
    • Tools for domain experts
    • Enable mediation between formats (MMS)
  • MarcOnt Ontology
    • Central point of MarcOnt Initiative
    • Translation and mediation format
    • Continuous collaborative ontology improvement
    • Knowledge from the domain experts
    • Community influence and evaluation
  • MarcOnt Ontology
    • Goals:
    • Capture concepts from the legacy bibliographic formats
      • MARC21, Bibtex, Dublin Core
      • Lattes, ...
    • Create a uniform bibliographic description format for digital libraries.
    • Enable the use of Semantic Web technologies (eg. reasoning) to improve capabilities of digital libraries
    • Improve interoperability
  • Format Translation Scenario

  • MarcOnt Tools
    • MarcOnt Initiative involves development of tools:
      • MarcOnt Portal – enabling collaborative ontology development
      • MarcOnt Mediation Services (MMS) – allows users to retrieve the description of the given bibliographic resource in multiple formats
      • RDF Translator – tool for data translation between formats using the set of given mapping rules
      • Rulegenerator – allows defining mapping (translation) rules between concepts from different ontologies.
